Exchange Online integration - Search for emails is not working anymoreDescriptionThe core feature of the existing 'Security Incident Response integration with Microsoft Exchange Online' (v10.5.5 or earlier), which involves searching for emails across the organization, is currently non-functional. This is due to the discontinuation of support for the 'New-ComplianceSearch' cmdlet in app-only authentication by Microsoft.We've received communication from the Microsoft team, via support ticket #2312190030003391, notifying us that they have currently discontinued support for the 'New-ComplianceSearch' cmdlet in app-only authentication (Certificate-based authentication). Unfortunately, this impacts our current integration, rendering it non-functional at the moment.The following is the notice from Microsoft -https://learn.microsoft.com/en-us/powershell/exchange/app-only-auth-powershell-v2?view=exchange-ps#:~:text=In%20Security%20%26%20Compliance,New%2DComplianceSearch Steps to Reproduce WorkaroundIn February 2024, we will roll out an upgraded store version of this integration. This release will replace the current 'New-ComplianceSearch' cmdlet, which interacts with PowerShell sessions on a MID server, with the enhanced advanced hunting functionality in Microsoft Defender for Office 365. https://learn.microsoft.com/en-us/graph/api/security-security-runhuntingquery?view=graph-rest-1.0&tabs=http However, it's important to note that customers will need to have ‘Microsoft Defender for Office 365 Plan 2’ for the new integration to function properly. This is the only recommended approach by Microsoft.Related Problem: PRB1729821
